Due to the number of different organic registration bodies, each of which has their own set of rules, it is suggested that you consult with your Carrs Fertilisers contact prior to making an organic fertiliser recommendation.

APPROVAL

Carrs Fertilisers submitted to have its organic brands registered with the Soil Association in April 2000 and is still awaiting a reply due to their backlog and constant changes to their registration system.

However, as the materials used in our organic fertilisers are generically approved by all of the organic bodies, organic farmers are free to use our products. As with all organic fertiliser products, the use of potash is restricted which means approval must be sought from the farmer's registration body prior to use.

RAW MATERIALS

Nitrogen:
There are no nitrogen fertilisers approved for organic use.

Phosphate:
Reactive Phosphate Rocks (RPR's) are generically permitted for unrestricted use.
Carrs Fertilisers Organic Choice products are based on Gafsa, the world's leading RPR (which is also used in our 'New Choice' and 'Scotphos' products). Gafsa RPR also provides other important nutrients, including calcium, magnesium, sodium, sulphur and trace elements (copper, cobalt, zinc, selenium and manganese).

Potash:
There are no sources of potash (other than charcoal and plant extracts) which are permitted for unrestricted use. Sulphate of Potash (SOP) and Sylvinite are approved for restricted use, subject to approval from the registration body.

Of these, Carrs Fertilisers use Sylvinite as SOP is too high in sulphur for most grassland systems and is also too acidifying. Sylvinite also provides a significant quantity of sodium, which is an important nutrient in an organic system.
